Dave -
Whether it was tee, me, or someone else, if your neighbor was upset by our comments, we certainly apologize - there was no offense meant.
If, on the other hand, you were the one who was bothered by what you apparently (incorrectly) perceived as an attack on your friend, then, as Salmonsmoker said, you need to lighten up. You're taking us (and, more importantly, yourself) much too seriously.
If you frequent BBQ-related sites you should pretty much expect to see a fair amount of humor (or attempted humor) directed at vegan & vegetarian lifestyles. If you feel a need to address those comments, you could more effectively do so in the spirit in which they were written instead of immediately getting your hackles up and branding someone as "narrow minded." If that "lighter" approach isn't combative enough for you, maybe you need to find somewhere else to hang out.
Jus' sayin'...
